Yes, foggy brain, fatigue, sinus pressure are all my symptoms with the drop of the barometric pressure. I often have a hard time with my thought process and even participating in conversations. In addition, my skin gets very dry and scaley when the barometric pressure drops.
Talk about misery....
I usually take an allergy pill or some type of antihistamine to deal with the symptoms. It does help a bit. I try to also stay indoors when I feel symptoms coming on.
